NFC Chip Authentication for Secure Payment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NFC payment systems have a low security level, as they allow information transmission without user authentication, making them vulnerable to unauthorized use if the device is lost or stolen.
Innovation Solution
Implementing a method where the NFC chip's information output function is initially disabled, and only enabled after successful user authentication, ensuring that information can only be transmitted if the user's identity is verified.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC payment function is enabled without authentication, then payment convenience is improved, but security level deteriorates
Solution Approach 1:
The system performs user authentication before enabling the NFC payment function. The authentication module verifies user identity in advance, and only after successful authentication does the system activate the NFC chip's information output capability. This preliminary security check prevents unauthorized payments while maintaining convenience for legitimate users.
2Speed
If NFC information output is always enabled, then transaction speed is improved, but vulnerability to unauthorized use increases
Solution Approach 1:
The NFC chip's information output function is designed to be dynamically controllable rather than statically enabled or disabled. The system can switch between enabled and disabled states based on authentication results and user actions. This dynamic control allows fast transactions when authenticated while preventing unauthorized access when the function remains disabled.
3Reliability
If user authentication is required before NFC payment, then security level is improved, but operation complexity increases
Solution Approach 1:
The authentication process leverages existing biometric or security systems already present in the terminal device (such as fingerprint sensors or password systems). These self-service authentication mechanisms are integrated into the NFC payment flow, providing security without requiring users to learn or carry additional authentication tools, thus minimizing the perceived complexity.

AI summary
The present disclosure relates to a method and a device for controlling information transmission and a smart terminal. The method includes: receiving an instruction for outputting information sent by a near field communication (NFC) chip, an information output function of the NFC chip being in a disabled state and information to be outputted being in an unavailable state; performing authentication of an identity of a user who triggers the information output; and if it is determined that the authentication of the identity is passed, enabling the information output function of the NFC chip and setting the information to be outputted as in an available state, such that the NFC chip can output the information. In the present disclosure, the information transmission through NFC can be more safe and reliable.
